Why the output is 4 downsample compared with input image? #231

If the original image is (H, W), the output of this segmentation is (H/4, W/4). If I want to obtain the segmentation result of (H, W), I need to upsampling the output? Am I right? I think the upsampling would provide a coarse result.

Why don't make the output of the network to be (H, W)? For example, in the last layer network, add a convtranspose layer.
